Apple’s new security protocol protects against quantum computing attacks

    Published on:

    As the technology industry debates whether fully fault-tolerant quantum computing will become a reality within the next decade, Apple (Nasdaq: AAPL) No chance. The tech giant has announced new security protocols that provide iMessage users with protection against quantum computing attacks.

    iPhone manufacturer explained This has been described as “the most significant encryption security upgrade in iMessage history.”

    Although not much of a threat today, quantum computing is expected to advance over the next decade. Quantum computers will be able to crack today's encryption standards, from RSA to elliptic curves. iMessage relies on the latter since his 2019.

    To prepare for advances in quantum computing, Apple could launch a “Harvest Now Decrypt Later” attack, where attackers steal large amounts of data in hopes of being decrypted when the technology catches up. That's what I think.

    To protect users of its instant messaging service, the Cupertino, California-based company announced PQ3, a post-quantum cryptography protocol.

    According to Apple, PQ3 is the most advanced protocol that provides Level 3 protection. Skype, Telegram, and WeChat are level 0 and do not offer end-to-end encryption by default. WhatsApp, Viber, Line, and the current iMessage versions were assigned Level 1, which has end-to-end encryption by default.

    Of the widely used messaging platforms, Signal is the closest to Level 2 encryption advancements, according to Apple. While Signal relies solely on post-quantum cryptography (PQC) key establishment, PQ3 adds continuous PQC rekeying.

    Signal president Meredith Whittaker commented on Apple's claims, saying the company considered updating its PQC keys but decided against it at the time.

    “Such approaches are currently an emerging area of ​​research, and implementation at Signal's scale requires solving existing problems.” Said One outlet.

    Apple's latest upgrade is expected to come with the general availability release of the next batch of software upgrades: iOS 17.4, macOS 14.4, iPadOS 17.4, and watchOS 10.4 in early March.
